It is RoHS compliant.

Key Features

• Capacitance & Voltage — 150 µF rated capacitance at 50 V with ±20% tolerance, suitable for power filtering and decoupling.
• Low Impedance for Switching Power Supplies — Part of the UPJ low-impedance series, intended for use in switching power supply applications.
• High Temperature Endurance — Rated for 5,000 hours at +105°C (life characteristics per series datasheet), enabling sustained operation under elevated temperature stress.
• Operating Temperature Range — −55°C to +105°C to cover a wide range of environmental conditions.
• Ripple Current Performance — Specified ripple current of 294.3 mA at 120 Hz (low frequency) and 545 mA at 200 kHz (high frequency), supporting effective ripple handling in power stages.
• Package & Mounting — Radial lead, can-type package with 12.5 mm diameter, 15 mm length, and 5 mm lead spacing for through-hole PCB layouts.
• Leakage & Loss Characteristics — Leakage current specified as not more than 0.03CV (µA) after 1 minute at 20°C; tan δ (loss tangent) max 0.10 at 50 V per series specifications.
• RoHS Compliant — Conforms to RoHS directive requirements.

Typical Applications

• Switching Power Supplies — Bulk and output filtering where low impedance and defined ripple-current capability reduce output ripple and improve regulation.
• DC-DC Converters — Input and output decoupling in converters where compact radial can parts are required for through-hole assemblies.
• Power Modules and Industrial Electronics — General-purpose smoothing and energy storage in power control and power distribution circuits operating within −55°C to +105°C.

Unique Advantages

• Low-Impedance Design: Enables effective high-frequency ripple suppression, supported by specified ripple-current ratings at 120 Hz and 200 kHz.
• Extended High-Temperature Life: Endurance rating of 5,000 hours at +105°C provides predictable performance over prolonged elevated-temperature operation.
