UPT2W270MHD

The UPT2W270MHD is a miniature, radial-lead aluminum electrolytic capacitor from Nichicon’s UPT series. It delivers high ripple-current capability and long operational life in a compact, radial can package for general-purpose high-voltage applications.

Specifically configured as a polarized 27 µF, 450 V capacitor, the UPT2W270MHD targets designs that require reliable high-voltage filtering and energy buffering with verified endurance and RoHS compliance.

Key Features

• Capacitance & Voltage — 27 µF nominal capacitance rated at 450 V DC, with capacitance tolerance of ±20% at 120 Hz, 20°C.
• High ripple-current performance — Rated ripple current of 250 mA at 120 Hz and 400 mA at 10 kHz, supporting demanding AC ripple environments.
• Compact radial can package — Radial-lead construction with 5.0 mm lead spacing and a compact footprint of L: 3.05 × D: 1.25 cm for space-constrained boards.
• Long life at elevated temperature — Endurance specified at 5000 hours at 105°C with DC bias plus rated ripple current applied; meets defined capacitance, tan δ and leakage criteria after test.
• Wide operating temperature range — Specified for –40°C to +105°C operation for use across varied ambient conditions.
• Electrical stability and leakage — Leakage current defined as not more than 0.06CV + 10 µA after 2 minutes’ application of rated voltage at 20°C; tangent of loss angle (tan δ) controlled (≤0.20 at 450 V, 120 Hz, 20°C).
• RoHS compliant — Manufactured to comply with RoHS directive requirements.

Typical Applications

• Lighting ballasts — Designed and noted as suited for ballast applications where elevated ripple tolerance and high-voltage handling are required.
• High-voltage power supplies — Filtering and energy storage in high-voltage DC link and smoothing stages using 450 V rated capacitance.
• Industrial electronics — High-voltage control and drive circuits that require compact, long-life capacitors with defined endurance at 105°C.

Unique Advantages

• High ripple capability: Rated ripple currents at both low and high frequencies (250 mA at 120 Hz, 400 mA at 10 kHz) reduce thermal stress and support stable operation under AC load.
• Compact high-voltage solution: Delivers 27 µF at 450 V in a miniature radial can, enabling high-voltage designs where PCB space is limited.
• Proven endurance: 5000-hour life at 105°C with DC bias and ripple verifies long-term performance for demanding thermal environments.
• Controlled electrical characteristics: Specified leakage current formula and tan δ limits provide predictable behavior for precision filtering and timing circuits.
• Wide temperature range: –40°C to +105°C rating supports deployment across a broad set of ambient conditions.
• Environmental compliance: RoHS conformity addresses regulatory requirements for lead-free manufacturing.
