Typical Applications

• General-purpose electronic circuits  Provides bipolar capacitance for general circuit functions where a 22 µF, 50 V capacitor is required.
• Through-hole PCB assemblies  Radial lead and 3.5 mm lead spacing enable straightforward insertion and soldering on through-hole boards.
• Wide-temperature installations  Suitable for equipment and modules that must operate across −55 °C to +105 °C.
• Long-life designs  Offers a 1000-hour endurance rating at 105 °C for designs that demand validated thermal endurance.

Unique Advantages

• Wide operating temperature capability: Supports −55 °C to +105 °C to cover a broad range of deployment environments.
• Bipolar construction: Eliminates polarity constraints common to polarized electrolytics, simplifying designs that require bidirectional voltage handling.
• Predictable electrical parameters: 22 µF ±20% with tan δ 0.14 and specified leakage current (33 µA) for reliable design margins and predictable behavior.
• Frequency-aware ripple performance: Rated ripple current values provided for 120 Hz and 10 kHz (63 mA and 126 mA respectively) to support designers accounting for frequency-dependent heating and ripple stress.
• Through-hole friendly package: Compact φ8 × 11.5 mm can and 3.5 mm lead spacing simplify mechanical integration and prototyping on through-hole PCBs.
• Endurance-tested: 1000 hours at 105 °C (with polarity inversion during the test) provides documented reliability data for thermal stress conditions.
