Key Features

• Capacitance & Voltage — 150 µF nominal capacitance with a 400 V rated voltage and ±20% tolerance at 120 Hz, 20°C.
• Long‑life Endurance — Specified to meet endurance requirements after 10,000 hours at 105°C when subjected to DC bias plus rated ripple current; capacitance change within ±25%, tan δ and leakage within defined limits.
• High Temperature Operation — Rated operating temperature range from −25°C to +105°C for 400 V variants in the LGR series.
• Ripple Current Capability — Rated ripple current of 820 mA at 120 Hz; 1.173 A at 50 kHz for this part. Frequency coefficients for the 400 V series are provided by the LGR datasheet (e.g., 0.77 at 50 Hz, 0.82 at 60 Hz, 1.00 at 120 Hz, 1.16 at 300 Hz, 1.30 at 1 kHz, 1.41 at 10 kHz, 1.43 at 50 kHz+).
• Leakage Current Characteristic — Leakage current specified by the series formula I ≤ 3√(C·V) µA after 5 minutes at 20°C (C in µF, V in V).
• Mounting & Package — Snap‑in terminal, radial can package for secure board mounting and mechanical stability in through‑hole assemblies.
• Regulatory — RoHS compliant as stated for the LGR series.
• Dimensions — Package approximate size L: 3 × D: 3 cm (radial can, snap‑in).

Typical Applications

• General‑purpose high‑voltage circuits — Where 150 µF at 400 V is required for energy storage and smoothing under elevated temperature conditions.
• Power supply bulk filtering — Suitable for DC bus smoothing and bulk capacitance in systems that operate up to 105°C and require long operational life.
• Industrial equipment — Applications requiring a snap‑in radial can for secure mounting combined with verified 10,000‑hour endurance at 105°C.

Unique Advantages

• Verified long‑life performance: Endurance testing at 105°C for 10,000 hours assures predictable capacitance, loss tangent and leakage behavior over extended field use.
• High voltage capability: 400 V rating enables use in higher‑voltage power rails without stacking multiple parts.
• Frequency‑aware ripple handling: Published frequency coefficients and ripple current ratings let engineers size capacitors accurately across low to high frequencies.
• Secure snap‑in mounting: Radial snap‑in terminals provide robust mechanical retention for through‑hole assemblies.
• Low leakage specification: Leakage current bounded by the series formula I ≤ 3√(C·V) µA supports predictable standby and no‑load current behavior.
• RoHS compliance: Conforms to RoHS requirements for regulated materials compliance.
