Compact Size, Strong Endurance: TS13C SMD Capacitors

  Suntan Technology Company Limited---- All Kinds of Capacitors

When equipment runs around the clock, capacitor failure isn’t just a maintenance issue — it’s a risk to your system’s stability. The TS13C Series SMD Aluminum Electrolytic Capacitors from Suntan are built for endurance, offering compact size without compromising thermal or electrical integrity.

Designed for Long-Hour, High-Demand Applications

Whether it’s a power supply buried inside a 24/7 industrial controller or a lighting driver installed in enclosed fixtures, TS13C is engineered to operate under stress. Its rated lifetime of 5,000 hours at 105°C, combined with stable electrical parameters, gives it the staying power needed for:

• Process automation systems

• Industrial LED power modules

• Motor controller boards in harsh environments

• Communication and network backup power designs

Thermal Durability in a Surface-Mount Package

The TS13C series is rated for continuous use up to +125°C, withstanding the heat generated inside compact enclosures or near heat-generating ICs. Its SMD-compatible form factor makes it ideal for modern PCB layouts where airflow is restricted, and convection cooling is minimal.

Key Technical Profile

• Voltage range: 160V – 450V

• Capacitance range: 3.3μF – 68μF

• Ripple current: up to 320mA at 120Hz

• Case sizes: 12.5mm to 16mm

• Leakage control: ≤ 0.04CV or 100μA

• RoHS and halogen-free compliant

What Makes TS13C a Long-Term Asset?

It’s not just about endurance — it’s about reducing unexpected downtime. With stable ESR, minimal leakage drift over time, and mechanical resilience in reflow assembly, TS13C reduces the need for rework and service calls, especially in high-temperature deployment.

When Compactness Meets Reliability

For many design teams, moving to SMD electrolytics comes with hesitation — thermal risk, shorter life, or higher ESR. TS13C was developed to close that gap, offering a proven alternative to bulky through-hole options with no compromise on stability.
