Key performance attributes include low-frequency and high-frequency ripple current capability, a broad operating temperature range, and long endurance at elevated temperature.

Note: This part is currently listed as End Of Life.

Key Features

• Capacitance & Voltage — 100 µF nominal capacitance with a rated voltage of 25 V and capacitance tolerance −20% to +20%.
• Loss Characteristic (tan δ) — tan δ = 0.13 measured at 20°C, 120 Hz, 25 V, providing a specified dissipation factor for AC performance evaluation.
• Ripple Current Handling — Low-frequency ripple current 180 mA at 120 Hz and high-frequency ripple current 450 mA at 100 kHz, suitable for designs exposed to both line-frequency and switching ripple.
• Leakage Current — Specified leakage current of 25 µA after rated-voltage application, useful for end-to-end leakage budgeting in power designs.
• Temperature & Endurance — Rated for operation from −40°C to 105°C with a life/endurance rating of 5000 hours at 105°C.
• Package & Mounting — Radial lead (can) package, size φ6.3 × 11 mm, lead spacing 2.5 mm (±0.5 mm), supplied bulk or bag packed (no terminal forming).
• Compliance — RoHS compliant.

Typical Applications

• General-purpose electronic circuits — Provides polarized bulk capacitance where a compact radial lead electrolytic is required.
• Power supply ripple control — Specified low- and high-frequency ripple current ratings support smoothing and decoupling in compact power stages where 25 V polarity is used.
• Industrial and consumer equipment — Rated for −40°C to 105°C and 5000 h endurance at 105°C, making it suitable for equipment with elevated operating temperatures.

Unique Advantages

• Compact radial can — φ6.3 × 11 mm package offers space-saving bulk capacitance for dense PCB layouts.
• Dual-frequency ripple capability — Defined ripple current values at 120 Hz and 100 kHz allow designers to size capacitors according to both line-frequency and switching-frequency ripple conditions.
• Engineered dissipation specification — tan δ specified at 20°C/120 Hz provides a clear reference for AC loss and thermal considerations.
• High-temperature endurance — 5000 hours at 105°C specification supports long-term performance in hotter environments.
• Clear mechanical details — Defined lead spacing (2.5 mm ±0.5 mm) and radial lead form simplify layout and assembly planning.
• RoHS compliant — Meets environmental directive requirements for restricted substances.
