Key Features

• Capacitance & Tolerance — 150 µF nominal with ±20% tolerance (measured at 120 Hz, 20°C), providing predictable energy storage for DC‑link and bulk filtering.
• High Voltage Rating — 450 V rated voltage for high‑voltage power rails and converter applications.
• High Ripple Current — Rated ripple current of 1.67 A at 120 Hz (105°C) and 2.672 A at 100 kHz, enabling reliable operation under significant AC stress.
• Extended High‑Temperature Endurance — 5000 hours at 105°C endurance with defined limits for capacitance change, tan δ, and leakage current after the test.
• Leakage & Loss Characteristics — Leakage current specified as 2800 µA (20°C, after 1 minute) and tan δ max 0.20 at 450 V (120 Hz), supporting predictable loss and self‑discharge behavior.
• Package & Mounting — Radial lead, φ18 × 46 mm can with 7.5 mm lead spacing for through‑hole assembly and mechanical robustness in power modules.
• Frequency Performance — Frequency coefficients provided (120 Hz = 1.00; 100 kHz = 2.15) for scaling ripple capability across frequency bands.
• Environmental & Qualification — RoHS compliant and AEC‑Q200 rated, supporting regulated production and automotive qualification requirements.

Typical Applications

• On‑Board Chargers and EV Power Electronics — Used for DC‑link smoothing and bulk energy buffering on high‑voltage charging systems where 450 V rating and long life are required.
• High‑Voltage Power Supplies — Provides stable capacitance and high ripple handling for industrial and commercial power converters operating at elevated voltages.
• Inverter and Motor Drive DC‑Link — Suitable for smoothing and filtering in inverter DC‑link stages where ripple current and temperature endurance are critical.
• Automotive Power Modules — AEC‑Q200 qualification and 105°C life enable use in automotive power electronics assemblies that demand durability and compliance.

Unique Advantages

• High ripple tolerance: Rated ripple currents of 1.67 A (120 Hz) and 2.672 A (100 kHz) reduce stress on thermal management and allow compact system designs.
• Robust high‑temperature life: 5000 hours at 105°C assures long operational life in elevated‑temperature environments common to power electronics.
• High‑voltage capability: 450 V rating supports DC‑link and high‑voltage converter topologies without series stacking.
• Automotive‑grade qualification: AEC‑Q200 rating provides a documented qualification path for vehicle electronics and related high‑reliability designs.
• Predictable leakage and loss: Specified leakage current and tan δ limits allow accurate thermal and leakage budgeting in system designs.
• Compact radial can format: φ18 × 46 mm package with 7.5 mm lead spacing simplifies replacement and through‑hole assembly in power modules.
