Key Features

• Rated Capacitance — 150 µF nominal capacitance with a tolerance of ±20% (measured at 120 Hz, 20°C).
• High Voltage Rating — 450 V rated voltage for high‑voltage power designs.
• Snap‑In Terminal, Radial Can — Snap‑in mounting type in a radial, can‑style package for secure PCB installation.
• High Ripple Current and Endurance — Specified as a high ripple current part with endurance to 3000 hours at 105°C under DC bias plus rated ripple current.
• Ripple Current Performance — Rated ripple current values include 1.31 A at 120 Hz and 1.873 A at 50 kHz for this part.
• Operating Temperature Range — Specified for −25°C to +105°C at the 450 V rating.
• Leakage Current Specification — Leakage current defined by I ≤ 3√(C·V) µA after five minutes at 20°C (C = µF, V = V).
• Impedance and Loss Characteristics — For 450 V parts, tan δ (max.) is 0.20 (measured at 120 Hz, 20°C); stability and impedance characteristics are defined for the 400–450 V range in the datasheet.
• Physical Dimensions — Size dimension L: 3.5 × D: 2.5 cm (radial can, snap‑in).
• RoHS Compliant — Meets RoHS directive requirements noted in product documentation.

Typical Applications

• General‑Purpose Power Supplies — Bulk energy storage and smoothing in circuits that require 450 V, 150 µF capacitance and high ripple endurance.
• Industrial Power Electronics — Components for industrial equipment where operation up to 105°C and sustained ripple current capability are required.
• High‑Ripple Environments — Designs that demand capacitors tested for 3000 hours application of rated ripple current at 105°C.

Unique Advantages

• Proven High‑Ripple Endurance — Endurance testing to 3000 hours at 105°C under rated ripple current supports reliable long‑term operation in ripple‑heavy circuits.
• High Voltage Capability — 450 V rating enables use in higher‑voltage power systems without changing capacitor topology.
• Snap‑In Mounting — Snap‑in terminals and radial can packaging provide robust mechanical retention for high‑reliability PCB assemblies.
• Clear Electrical Limits — Leakage current and tan δ limits are specified in the datasheet, enabling straightforward validation during design and test.
• Wide Operating Temperature — Specified operation from −25°C to +105°C for the 450 V range accommodates elevated ambient and thermal conditions.
• RoHS Compliance — Conforms to RoHS directives for environmentally constrained designs.
