UEP2A100MPD

The UEP2A100MPD is a bi-polarized aluminum electrolytic capacitor in a radial-can package designed for general-purpose applications. It combines a 10 µF capacitance with a 100 V rating and a compact radial lead form factor for straightforward integration into through-hole designs.

Key value comes from a wide operating temperature range of −55 °C to +105 °C, RoHS compliance, and endurance characterized to 1000 hours at 105 °C with polarity inversion every 250 hours, making it suitable where stable bipolar performance and predictable aging are required.

Key Features

• Capacitance & Tolerance — 10 µF nominal with ±20% tolerance at 120 Hz, 20 °C; suitable for general-purpose decoupling and coupling tasks where a bipolar electrolytic is required.
• Voltage Rating — 100 V rated voltage for higher-voltage circuits where a compact bipolar capacitor is needed.
• Bi-Polarized Construction — Bi-polarized capacitor architecture allowing operation with polarity inversion; endurance testing specifies polarity inversion every 250 hours during a 1000 hour test at 105 °C.
• Wide Temperature Range — Specified for −55 °C to +105 °C operation, supporting designs that span wide ambient and operating conditions.
• Reliability & Endurance — Endurance specification: rated voltage applied for 1000 hours at 105 °C with defined limits on capacitance change, tan δ, and leakage current after recovery to 20 °C.
• Leakage Current — After 5 minutes’ application of rated voltage at 20 °C, leakage current is specified as not more than 0.03CV (µA), enabling predictable leakage behavior for sizing and bias considerations.
• Loss Tangent (tan δ) — Maximum tan δ of 0.10 at the 100 V rating (measured at 120 Hz, 20 °C), useful for assessing AC loss in filtering and coupling applications.
• Ripple Current Performance — Rated ripple current specified as 50 mA at 120 Hz and 100 mA at 10 kHz; frequency coefficients for 10–47 µF parts allow scaling ripple capability across frequencies.
• Radial Lead Package — Radial lead (can) package with 3.5 mm lead spacing, φd = 0.6 mm leadwire, compact footprint (L: 1.15 × D: 0.8 cm) for through-hole assemblies.
• Environmental Compliance — RoHS compliant and sleeved/marked with white printing on a black sleeve for clear identification.

Typical Applications

• General-purpose electronics — Use where a compact bipolar electrolytic capacitor is needed for AC coupling, decoupling, or signal-path tasks across a wide temperature range.
• Industrial control modules — Suitable for control and instrumentation circuits that require bipolar operation and stable performance up to 105 °C.
• Power-supply subsystems — Applicable for local filtering and ripple attenuation in higher-voltage supply sections that accept radial through-hole components.

Unique Advantages

• Wide operating temperature span — −55 °C to +105 °C rating supports designs exposed to broad ambient or thermal environments.
• Bipolar capability with defined endurance — Designed for polarity inversion during endurance testing (inverted every 250 hours over 1000 hours at 105 °C), providing a verifiable lifecycle metric.
• High voltage in a compact package — 100 V rating combined with a small radial-can footprint (1.15 × 0.8 cm) enables higher-voltage design choices without a large board area impact.
• Predictable leakage specification — Leakage limited to 0.03CV (µA) after initial application improves predictability for bias-sensitive circuits.
• Frequency-aware ripple handling — Specified ripple current values and frequency coefficients for the 10–47 µF range make it easier to size for AC ripple across frequencies.
• Regulatory compliance — RoHS-compliant construction for environmentally restricted designs.

Why Choose UEP2A100MPD?

UEP2A100MPD positions itself as a compact, bi-polar aluminum electrolytic solution for general-purpose designs that require 100 V capability and stable operation across −55 °C to +105 °C. Its defined endurance behavior and leakage limits make it easier to predict long-term performance in applications where polarity reversal or AC operation may occur.

This part is well suited to engineers specifying through-hole, radial-can capacitors for industrial, instrumentation, and power-supply subsystems that value verifiable endurance data, a clear ripple current specification, and RoHS compliance from a recognized manufacturer.
