UHE1H3R3MDD

The UHE1H3R3MDD is a miniature, radial-lead aluminum electrolytic capacitor in Nichicon’s UHE series. It delivers 3.3 µF capacitance at a 50 V rating in a compact φ5 × 11 mm can with 2.0 mm lead spacing, designed for general-purpose power-filtering and decoupling applications.

Engineered for low loss and long-term operation, this polarized capacitor is specified for operation from −40 °C to 105 °C and provides controlled leakage, low tangent of loss angle, and specified ripple-current performance across low and high frequencies.

Key Features

• Capacitance & Voltage — 3.3 µF nominal capacitance rated at 50 V for general-purpose DC decoupling and filtering.
• Tight Loss Characteristics — tanδ of 0.10 measured at 20 °C, 120 Hz, supporting low-impedance behavior in AC ripple environments.
• Compact Radial Package — φ5 × 11 mm radial can with 2 mm lead spacing (±0.5 mm) for space-constrained through‑hole designs.
• Temperature & Endurance — Operating range −40 °C to 105 °C with a rated life of 5000 hours at 105 °C.
• Controlled Leakage — Specified leakage current of 3 µA (measured after application of rated voltage per product test condition).
• Ripple Current Performance — Low-frequency ripple current of 29.15 mA at 120 Hz and high-frequency ripple current of 53 mA at 10 kHz, enabling predictable behavior across common ripple spectra.
• Polarized Construction & Tolerance — Polarized aluminum electrolytic with capacitance tolerance of −20% to +20%.
• RoHS Compliant & Packaging — RoHS-compliant; available in bulk (no terminal forming) or bag packing.

Typical Applications

• General-purpose power filtering — Small-value bulk or smoothing capacitor in low-current DC power rails where 50 V rating and compact size are required.
• Decoupling for compact boards — Local decoupling on compact, through-hole assemblies benefiting from the radial can form factor and 2 mm lead spacing.
• Signal and bias stabilization — Use where low leakage and controlled tanδ are important for maintaining bias levels and signal integrity.
• Frequency-dependent ripple environments — Applications that require defined ripple-current capability at both low (120 Hz) and higher (10 kHz) frequencies.

Unique Advantages

• Small footprint, proven form factor — φ5 × 11 mm radial can saves board area while keeping through-hole reliability and simple mounting.
• Predictable AC performance — Specified tanδ and ripple-current values provide designers measurable parameters for thermal and lifetime calculations.
• Wide operating temperature — −40 °C to 105 °C rating supports deployment across a broad range of environmental conditions.
• Clear lifetime specification — 5000 hours at 105 °C gives a defined endurance metric for thermal stress planning and reliability assessments.
• Low leakage for bias stability — 3 µA leakage current supports circuits where minimal DC loss is required.
• RoHS compliance — Meets RoHS requirements for environmentally conscious designs.

Why Choose UHE1H3R3MDD?

UHE1H3R3MDD combines a compact radial-can package with defined electrical and thermal characteristics—3.3 µF at 50 V, low tanδ, controlled leakage, and specified ripple currents—making it a straightforward choice for general-purpose filtering and decoupling in compact through-hole assemblies. Its −40 °C to 105 °C operating range and 5000-hour life at 105 °C give you measurable parameters for reliability planning in moderate-temperature applications.

This part is well suited to engineers and purchasers specifying polarized aluminum electrolytic capacitors where small size, predictable AC behavior, and documented endurance are key selection criteria.
