UPT2W330MHD

The UPT2W330MHD is a Nichicon UPT series aluminum electrolytic capacitor: a miniature, radial-lead polarized can designed for general-purpose circuitry and ballast applications. It delivers 33 µF capacitance at a 450 V rating in a compact L: 3.55 × D: 1.25 cm footprint, offering a combination of high voltage, high ripple capability and extended life.

Key value propositions include high ripple-current handling, a long 5,000 hour life at 105°C, and a wide operating temperature range (−40°C to 105°C), making it suitable where stable performance under thermal and ripple stress is required.

Key Features

• Electrical Rating — 33 µF nominal capacitance with a 450 V rated voltage and polarization as an electrolytic capacitor; capacitance tolerance ±20%.
• High Ripple Performance — Rated ripple current of 280 mA at 120 Hz and 448 mA at 10 kHz, with frequency coefficients available across common ripple frequencies for design scaling.
• Long Endurance — Designed for 5,000 hours of operation at 105°C under DC bias plus rated ripple current; endurance criteria specify capacitance within ±20% and leakage current within initial specified limits after the test.
• Temperature Range — Operating range from −40°C to +105°C to cover a wide set of ambient conditions.
• Compact Radial Lead Package — Radial lead, can-style package with 5 mm lead spacing for through-hole mounting and straightforward PCB implementation; physical size L: 3.55 × D: 1.25 cm supports space-constrained designs.
• Leakage and Loss Characteristics — Leakage current specified as not more than 0.06CV + 10 µA (after 2 minutes at 20°C), and specified tan δ limits per rated voltage for predictable loss behavior.
• Environmental Compliance — RoHS compliant.

Typical Applications

• Ballast Applications — Specifically called out in the product literature; suited where high ripple current capability and high-voltage endurance are required.
• General‑Purpose Electronic Circuits — Polarized radial-lead electrolytic for general-purpose use where a 33 µF / 450 V capacitor is required.
• High‑Ripple Environments — Designs that impose significant AC ripple on DC bus or filter components benefit from the UPT2W330MHD’s rated ripple current and frequency scaling data.

Unique Advantages

• High Ripple Tolerance: Explicit ripple ratings (280 mA at 120 Hz, 448 mA at 10 kHz) let you size the capacitor precisely for AC stress conditions.
• Extended High‑Temperature Life: 5,000 hours at 105°C demonstrates sustained performance under elevated-temperature operation.
• Compact, Serviceable Package: Small can-type radial package with 5 mm lead spacing simplifies through-hole assembly and replacement in constrained layouts.
• High Voltage Capability: 450 V rating supports high-voltage DC bus and ballast circuits without series stacking.
• Predictable Leakage Behavior: Leakage current limit formula (0.06CV + 10 µA after 2 minutes at 20°C) provides a verifiable upper bound for power-loss and standby leakage calculations.
• Regulatory Compliance: RoHS compliance supports deployment in designs requiring restricted substance conformance.

Why Choose UPT2W330MHD?

The UPT2W330MHD combines a high 450 V rating, compact radial-can footprint and specifically rated high ripple current — attributes that suit it to ballast circuits and other general-purpose applications exposed to AC ripple and elevated temperatures. Its defined leakage and tan δ characteristics, together with a 5,000 hour life at 105°C, provide predictable long-term behavior for engineering validation.

This capacitor is ideal for engineers and procurement teams specifying components for high-voltage, high-ripple environments that require a through-hole, replaceable part with verifiable endurance and RoHS compliance.
