UPS1H4R7MDD

The UPS1H4R7MDD is a miniature, radial-lead aluminum electrolytic capacitor designed for high-reliability general-purpose and switching power supply applications. It delivers a compact 4.7 µF, 50 V polarized solution with low impedance characteristics and a wide operating temperature range of −55°C to 105°C.

Key value comes from its small φ5 × 11 mm can, measurable low-frequency and high-frequency ripple handling, and an established endurance rating for thermal stress—making it suitable for space-constrained power-decoupling tasks. Status: End Of Life.

Key Features

• Capacitance & Voltage — 4.7 µF rated capacitance with a 50 V rating and ±20% tolerance for predictable decoupling and filtering performance.
• Low Loss / Tangent of Loss Angle — tan δ = 0.10 measured at 20°C, 120 Hz, supporting stable AC performance at the rated voltage.
• Ripple Current Capability — Specified low-frequency ripple current of 15.3 mA (120 Hz) and high-frequency ripple current of 90 mA (10 kHz), useful for both bulk and higher-frequency filtering.
• Leakage Current — Typical leakage current 7.05 µA, enabling low standby losses in long-term DC applications.
• Wide Temperature Range — Rated for −55°C to 105°C to cover demanding environmental conditions.
• Endurance — Life/endurance rating of 2000 hours at 105°C for designs requiring defined high-temperature performance.
• Compact Radial Can — φ5 × 11 mm package with 2 mm lead spacing (±0.5 mm) in a radial, can-style case for easy through-hole mounting and dense PCB layouts.
• Packaging Options — Available in bulk (no terminal forming) or bag packing to match assembly preferences.
• RoHS Compliant — Meets RoHS directive requirements for restricted substances.

Typical Applications

• Switching Power Supplies — Local decoupling and output smoothing where compact, low-impedance capacitors are required.
• General Purpose Power Filtering — Bulk and bypass filtering in small power rails and control circuits using a 50 V rating.
• Embedded and Industrial Electronics — Space-constrained boards and modules that require a wide −55°C to 105°C operating temperature range.

Unique Advantages

• Space-efficient form factor: φ5 × 11 mm radial can offers high capacitance density for compact PCB layouts.
• Designed for AC ripple handling: Specified ripple currents at both 120 Hz and 10 kHz enable use across low- and higher-frequency filtering duties.
• Wide operational temperature: −55°C to 105°C rating supports deployment across varied thermal environments.
• Defined endurance: 2000 hours at 105°C gives predictable lifetime performance for thermal-stressed designs.
• Low leakage: 7.05 µA leakage current supports low-loss DC storage and standby conditions.
• RoHS compliant: Conforms to RoHS for regulatory and environmental compatibility.
