UPW1A330MDD

The UPW1A330MDD is a 33 µF, 10 V miniature aluminum electrolytic capacitor in a radial‑lead can designed for low impedance and high reliability in compact switching power supply applications. It combines a small footprint (L: 1.1 × D: 0.5 cm) with automotive‑grade qualification to support demanding power electronics environments.

Optimized for board‑level power decoupling and filtering, this polarized radial‑lead part delivers targeted ripple handling and a wide operating temperature range for robust performance across applications.

Key Features

• Capacitance & Voltage: 33 µF nominal capacitance at a 10 V rated voltage, with ±20% tolerance for predictable DC performance.
• Miniature radial can package: Compact package dimensions (L: 1.1 × D: 0.5 cm) with 2 mm lead spacing make the part suitable for space‑constrained board layouts.
• Low impedance design: Engineered for low ESR to support switching power supply decoupling; specified ripple currents of 54 mA at 120 Hz and 180 mA at 10 kHz demonstrate frequency‑dependent ripple handling.
• Wide temperature range: Specified operating temperature from −55 °C to +105 °C to cover harsh thermal conditions.
• Automotive qualification: AEC‑Q200 rating for the series, providing a reliability baseline for automotive and similarly demanding applications.
• Endurance and lifetime: Rated for 2000 hours at 105 °C, enabling predictable life‑cycle planning in elevated‑temperature environments.
• Low leakage characteristic (series spec): Series leakage current spec of ≤ 0.03CV (µA) after 1 minute at 20 °C provides controlled standby losses for precision power designs.
• Polarized for DC applications: Radial lead, polarized construction suited for DC filtering and bulk decoupling roles.

Typical Applications

• Switching power supplies: Local output filtering and decoupling where low impedance and compact size reduce voltage ripple and board space.
• Automotive electronics: Power filtering and smoothing in automotive control modules and electronic subsystems, leveraging the AEC‑Q200 rating.
• Compact DC‑DC converters: Onboard energy storage and decoupling in space‑constrained converter designs.

Unique Advantages

• Space‑efficient form factor: Small L × D footprint and radial lead package allow placement in tight layouts without sacrificing capacitance.
• Designed for switching environments: Low impedance and specified ripple current values at 120 Hz and 10 kHz support effective smoothing of switching noise across common switching frequencies.
• Temperature resilience: −55 °C to +105 °C operating range and 2000‑hour high‑temperature lifetime enable reliable operation in elevated thermal conditions.
• Automotive‑grade reliability: AEC‑Q200 rating indicates the UPW series is designed with automotive reliability considerations in mind.
• Predictable electrical behavior: ±20% capacitance tolerance and defined leakage limits make performance predictable for power budgeting and DC behavior.
