UPM2W330MHD

The UPM2W330MHD is a radial lead aluminum electrolytic capacitor from Nichicon’s UPM series, specified at 330 µF and 450 V. It is optimized for high-voltage, high-reliability applications and offers low impedance characteristics alongside defined ripple handling and leakage performance.

This part is rated for operation from -25 °C to 105 °C with a 5000-hour endurance at 105 °C and carries AEC-Q200 designation. Note: the product status is End Of Life.

Key Features

• Rated capacitance and voltage — 330 µF at 450 V, suitable for high-voltage DC circuits requiring substantial capacitance.
• Capacitance tolerance & dielectric loss — ±20% tolerance; tanδ = 0.26 (measured at 20 °C, 120 Hz), allowing predictable AC loss behavior for design verification.
• Ripple current capability — Low-frequency ripple current 170 mA at 120 Hz and high-frequency ripple current 272 mA at 200 kHz, supporting both mains-frequency and switching environments.
• Leakage current — Specified leakage current of 694 µA for initial screening and thermal/stability considerations.
• Endurance — 5000 hours at 105 °C under rated conditions, providing long-term stability in elevated temperature environments.
• Operating temperature range — -25 °C to 105 °C to cover a broad set of thermally demanding use cases.
• Package and mechanical — Radial lead, can-style package with physical size φ18 × 40 L and lead spacing 7.5 mm (lead spacing tolerance ±0.5 mm); available in bulk (no terminal forming) or bag packing.
• Compliance — RoHS compliant and AEC-Q200 rated as indicated in the product specifications.
• Status — End Of Life; consult availability before specifying in new designs.

Typical Applications

• Automotive high-voltage systems — Suited for in-vehicle circuits that require 450 V rated capacitance with AEC-Q200 qualification and extended endurance at elevated temperatures.
• Power electronics modules — Used where a 330 µF, 450 V electrolytic capacitor is required to support DC bus or high-voltage smoothing functions while meeting ripple and leakage constraints.
• High-temperature environments — Applicable in assemblies operating up to 105 °C for up to 5000 hours when long-term stability is required.

Unique Advantages

• High-voltage bulk capacitance: 330 µF at 450 V delivers substantial energy storage in a compact radial-can package for high-voltage designs.
• Defined ripple performance: Separate low- and high-frequency ripple current ratings (170 mA @120 Hz, 272 mA @200 kHz) let engineers size thermal and ripple margins accurately.
• Long endurance at elevated temperature: 5000-hour life at 105 °C supports long-term reliability in demanding thermal environments.
• AEC-Q200 rating: Provides an explicit qualification path for automotive applications that require recognized component-level reliability.
• Through-hole radial form factor: Radial leads and standard lead spacing (7.5 mm) ease assembly and retrofit into existing through-hole layouts.
• Regulatory compliance: RoHS compliant for environmentally conscious designs.

Why Choose UPM2W330MHD?

UPM2W330MHD combines high-voltage capability (450 V) with a large capacitance (330 µF) and defined electrical characteristics—tanδ, leakage current, and frequency-specific ripple ratings—so designers can evaluate thermal and electrical tradeoffs precisely. The radial-can package and mechanical dimensions make it straightforward to integrate into through-hole boards or replace legacy high-voltage bulk capacitors.

With a 5000-hour endurance at 105 °C and AEC-Q200 designation, this part is positioned for high-reliability automotive and industrial use cases where long-term performance under elevated temperature and voltage is a key requirement. Because the part is End Of Life, confirm current stock and suitable alternatives when planning production designs.
