UVP1E331MHD

The UVP1E331MHD is a bi-polarized aluminum electrolytic capacitor from the UVP series, designed for entertainment electronics and general-purpose applications. It combines a 330 µF capacitance with a 25 V rated voltage in a radial-lead can package, offering reliable AC-capable performance where polarity reversal can occur.

Engineered for practical field use, the component delivers defined ripple-current capability and endurance across a -40°C to +85°C operating range, and is RoHS compliant for modern consumer-electronics designs.

Key Features

• Capacitance & Voltage: 330 µF nominal capacitance with a 25 V rated voltage and ±20% tolerance at 120 Hz, 20°C.
• Bi-Polar Construction: Bi-polarized design suited for AC or polarity-reversing circuits commonly found in entertainment electronics.
• Package & Mounting: Radial-lead can with 5 mm lead spacing and compact dimensions (L: 2 cm × D: 1.25 cm) for PCB through-hole mounting.
• Temperature Range & Endurance: Rated for –40°C to +85°C with a specified endurance of 2000 hours at 85°C (with polarity inversion every 250 hours) and defined post-test limits for capacitance, tan δ, and leakage current.
• Ripple Current Handling: Rated ripple current of 450 mA at 120 Hz and 675 mA at 10 kHz, addressing both low- and high-frequency ripple scenarios.
• Leakage & Dissipation: Leakage current specified as not more than 0.03CV (µA) after 5 minutes at 20°C; tan δ limits per series specification (0.20 max. at 25 V rating).
• Low-Temperature Stability: Impedance performance characterized down to –40°C (Z(–25°C)/Z(+20°C) = 2; Z(–40°C)/Z(+20°C) = 5 for 25 V rating), supporting stable operation across the rated temperature span.
• Environmental Compliance: RoHS compliant (2011/65/EU, (EU)2015/863).
• Identification: Marked with white letters on a black sleeve for clear polarity/part marking.

Typical Applications

• Entertainment Electronics: Used in audio and video consumer equipment where bi-polar operation and AC-coupling are required, leveraging the 330 µF capacitance and 25 V rating.
• Power Filtering and Decoupling: Provides bulk capacitance and ripple smoothing in power-supply sections of consumer devices, with specified ripple-current capability at 120 Hz and 10 kHz.
• Signal Coupling and AC Networks: Suitable for AC-coupling or bipolar signal-path circuits in general-purpose consumer-electronics designs due to its bi-polarized construction.

Unique Advantages

• Bi-polarized flexibility: Eliminates the need for polarity-specific placement in circuits that experience AC or polarity reversal, simplifying layout and assembly.
• Defined ripple performance: Published ripple-current ratings at 120 Hz and 10 kHz allow predictable thermal and electrical design decisions for both low- and high-frequency applications.
• Compact radial-can form factor: Small footprint (2.0 × 1.25 cm) with 5 mm lead spacing enables dense through-hole placement on PCBs used in consumer equipment.
• Thermal and long-term reliability: Rated endurance of 2000 hours at 85°C with specified post-test limits provides quantifiable lifecycle expectations for product development and qualification.
• Low leakage specification: Leakage current defined as ≤ 0.03CV (µA) after 5 minutes at 20°C supports low-standby and precision applications where leakage matters.
• Regulatory compliance: RoHS conformity supports use in markets requiring restricted-substance compliance.
