Long Life vs Standard Radial Electrolytic Capacitors

SUNTAN TECHNOLOGY COMPANY LIMITED · ALL KINDS OF CAPACITORS

Long life vs standard radial electrolytic capacitors influences power supply lifetime, SMPS output stability, and LED driver reliability. Engineers evaluating an aluminum electrolytic capacitor must consider endurance hours, temperature rise, and ripple current stress together, as these factors define real operating life.

---

Understanding Electrolytic Capacitor Endurance Ratings

The endurance rating (2000h, 5000h, 10000h) indicates how long the capacitor maintains electrical characteristics at rated temperature and ripple current. As electrolyte evaporates over time, ESR increases and capacitance decreases, leading to ripple voltage rise and potential instability.

Class	Endurance @105°C	Typical Usage	Expected Duty
Standard	2000h	General electronics	Intermittent
Long Life	5000h	LED drivers / controls	Extended use
High Endurance	10000h	SMPS / telecom	Continuous

---

Temperature Acceleration Model

Electrolytic capacitor lifetime follows temperature acceleration behavior. Life approximately doubles for each 10°C drop in core temperature. Ripple current heating raises internal temperature above ambient, shortening effective endurance.

Lifetime estimation relationship:

L₂ = L₁ × 2^{((T₁ − T₂)/10)}

---

Ripple Current Influence

Ripple current flowing through ESR generates internal heat (I²R loss). As ESR increases with aging, heating rises further, accelerating electrolyte dry-out in a feedback mechanism. This explains why SMPS output capacitors and LED driver capacitors require higher endurance classes.

---

Design Stage Selection Strategy

Engineers should base selection on:

• RMS ripple current
• Ambient and PCB thermal zones
• Expected service life
• Enclosure airflow

---

Field Failure Symptoms of Underrated Capacitors

When standard endurance capacitors are used in high ripple or high temperature environments, typical field symptoms appear gradually rather than as sudden failure.

• Output ripple voltage increase
• LED driver flicker over time
• SMPS regulation instability
• Rising ESR detected in maintenance testing
• Reduced hold-up time in power supplies

These behaviors are wear-out mechanisms caused by electrolyte dry-out, not dielectric breakdown. Selecting long life capacitors prevents these progressive degradation issues.

2016 vs 3215 vs 3225 SMD Quartz Crystal Comparison

SUNTAN TECHNOLOGY COMPANY LIMITED · ALL KINDS OF CAPACITORS

2016 vs 3215 vs 3225 SMD Quartz Crystal Comparison

When selecting an SMD quartz crystal, package size is often the first parameter engineers consider. However, choosing between 2016, 3215, and 3225 packages involves more than mechanical constraints alone. Electrical behavior, frequency range, and application requirements all play a critical role in effective SMD quartz crystal selection.

This article provides a practical SMD quartz crystal comparison to help engineers quickly determine which package is best suited for MCU clock crystal and RTC crystal 32.768kHz applications.

---

Why Package Size Matters — and Why It’s Not Enough

Smaller SMD quartz crystal packages help reduce PCB footprint, but they typically introduce higher ESR and tighter oscillator startup margins. Larger packages generally provide improved oscillation stability and greater electrical tolerance. Understanding this trade-off is essential when comparing 2016 vs 3215 vs 3225 SMD quartz crystals.

---

2016 vs 3215 vs 3225: Key Differences

Package	Typical Frequency Range	Typical Application	Design Consideration
2016 (2.0 × 1.6 mm)	20–54 MHz	Compact MCU, wireless modules	Higher ESR, reduced startup margin
3215 (3.2 × 1.5 mm)	32.768 kHz	RTC, low-power timekeeping	Tuning fork structure, ultra-low power
3225 (3.2 × 2.5 mm)	12–54 MHz	Industrial MCU, control systems	Lower ESR, stable oscillation

---

Which SMD Quartz Crystal Should You Choose?

For MCU clock crystal applications operating in the MHz range, the 3225 package is often preferred when PCB space allows, due to its lower ESR and more stable oscillator startup behavior.

The 2016 package is suitable for highly compact designs but requires careful validation of oscillator conditions, particularly in low-drive MCU circuits.

For real-time clock applications, the 3215 SMD quartz crystal is specifically designed for RTC crystal 32.768kHz operation and should not be substituted with general-purpose MCU crystals.

Why choose the TS04S Double-Sided Metallized Polypropylene Axial Capacitor Operates as a Non-Polar Film Capacitor

SUNTAN TECHNOLOGY COMPANY LIMITED · ALL KINDS OF CAPACITORS

TS04S double-sided metallized polypropylene axial film capacitor for high-voltage, low-loss power electronics.

This guide explains why the TS04S double-sided metallized polypropylene axial capacitor behaves as a non-polar film capacitor and how it can be used safely in AC and pulse circuits. It is written for design engineers, distributors and OEMs who need reliable axial film capacitors for high-dielectric strength applications.

1. Why Non-Polar Axial Film Capacitors Matter

Polypropylene film capacitors with double-sided metallization, such as the TS04S, are inherently non-polar. The dielectric is an insulating polypropylene film, and the electrode layers are applied on both sides of the film, so there is no “positive” or “negative” terminal required for normal operation.

• Support for AC and bidirectional pulse signals without reverse-voltage damage
• Stable capacitance and low ESR over time
• Reduced assembly errors and simplified PCB layout (no polarity marking required)
• Long service life and strong thermal resilience compared with many electrolytics

In applications where the voltage reverses or the waveform is symmetrical (AC coupling, snubber networks, timing circuits), non-polar film capacitors like TS04S are a safer and more predictable choice than polarized capacitors.

2. Technical Advantages and Cross-Brand Compatibility

The TS04S series is available across a broad voltage range and multiple can sizes, which gives distributors and OEMs flexible stocking options and easier cross-reference mapping against other brands.

• High-voltage PP axial options for demanding power electronics
• Double-sided metallization supports controlled self-healing at localized faults
• Low dielectric loss suitable for precision and high-frequency circuits
• Cross-brand replacement lists and datasheets available for sourcing and qualification

For distributors, this means one TS04S family can cover multiple part numbers from other manufacturers, while maintaining consistent electrical performance and mechanical fit.

3. Applications Optimized for TS04S

Typical use cases where TS04S non-polar axial film capacitors are especially effective:

• Timing circuits and pulse shaping where low loss and stable capacitance are critical
• SMPS, LED drivers and inverters using high-voltage, high-frequency switching
• AC filtering and snubber networks across relays, SCRs and power semiconductors
• Precision and industrial-grade circuits requiring long-term stability and low drift
