UAQ2D151MHD

The UAQ2D151MHD is a radial-lead aluminum electrolytic capacitor in a φ16 × 30.5 mm can, offering 150 µF capacitance at a 200 V rating with ±20% tolerance. It is designed for general-purpose electronic applications that require elevated ripple handling and wide operating temperature range.

Key design attributes include high ripple current capability across low and high frequencies, a wide operating temperature range from -40°C to 105°C, an improved safety feature for abnormal over-voltage conditions, and a rated endurance of 2000 hours at 105°C.

Key Features

• Capacitance & Voltage — 150 µF nominal capacitance rated at 200 V with ±20% tolerance (120 Hz, 20°C).
• High Ripple Current — Rated ripple current of 435 mA at 120 Hz and 696 mA at 10 kHz, supporting applications with significant AC ripple components.
• Wide Temperature Range — Operates from -40°C to 105°C to support elevated temperature environments.
• Endurance — 2000 hours life at 105°C when subjected to D.C. bias plus rated ripple current, with specified limits for capacitance change, tan δ, and leakage current after test.
• Leakage & Loss — Specified leakage current 1300 µA and tan δ max 0.15 (measured at 120 Hz, 20°C at rated voltage).
• Safety Feature — Series-level improved safety design for abnormally excessive voltage and a pressure relief vent to mitigate hazardous failure modes under abnormal conditions.
• Form Factor & Mounting — Radial lead, can-style package (φ16 × 30.5 mm) with 7.5 mm lead spacing; supplied bulk (no terminal forming) in bag packing.
• RoHS Compliant — Conforms to RoHS (2011/65/EU, (EU)2015/863) requirements.

Typical Applications

• General Purpose Electronic Equipment — For systems requiring a 200 V, 150 µF radial electrolytic capacitor for bulk capacitance and energy storage.
• Power Circuitry and Ripple Management — Suited for designs that require higher ripple current capability, as characterized by specified 120 Hz and 10 kHz ripple ratings.
• Industrial and Repair/Replacement Use — Can be used to match existing designs or replace like-for-like components where the electrical and physical dimensions align.

Unique Advantages

• High-frequency ripple tolerance — Rated ripple current up to 696 mA at 10 kHz helps manage AC components in switching environments.
• Wide operating temperature window — −40°C to 105°C supports deployment across a broad range of environmental conditions.
• Safety-focused construction — Improved abnormal-voltage protection and pressure relief vent provide an extra margin of safety under over-voltage conditions.
• Compact radial can package — φ16 × 30.5 mm can with 7.5 mm lead spacing provides a compact footprint for through-hole assemblies.
• Defined endurance specification — 2000 hours at 105°C with post-test limits on capacitance, tan δ and leakage for predictable lifetime behavior.
• Regulatory compliance — RoHS-compliant construction for restricted substances control.

Why Choose UAQ2D151MHD?

UAQ2D151MHD combines a 150 µF / 200 V rating with elevated ripple capabilities and a wide −40°C to 105°C operating range, making it a practical choice for general-purpose electronic designs that need reliable bulk capacitance in a radial-lead can.
