UVR1H3R3MDD

The UVR1H3R3MDD is a miniature aluminum electrolytic capacitor from Nichicon’s UVR series, offered as a radial-lead, can-style component for general-purpose electronics. It provides 3.3 µF nominal capacitance at a 50 V rating with a compact φ5×11L footprint and 2 mm lead spacing.

Designed for space‑conscious designs and entertainment electronics, this part combines low leakage and defined ripple-current capability with a 2000 hour endurance at 85 °C for reliable operation in consumer and general-purpose applications.

Key Features

• Capacitance & Tolerance: 3.3 µF nominal capacitance with ±20% tolerance measured at 120 Hz, 20 °C.
• Voltage Rating: 50 V rated voltage suitable for mid-voltage power rails and decoupling tasks.
• Low Leakage: Measured leakage current of 4.95 µA to reduce standby losses and preserve circuit bias over time.
• Loss Angle (tan δ): tan δ of 0.12 (measured at 120 Hz, 20 °C) for predictable AC loss characteristics.
• Ripple Current Capability: 35 mA at 120 Hz (low frequency) and 70 mA at 10 kHz (high frequency) to handle typical ripple and smoothing requirements.
• Thermal & Life Performance: Rated for operation from −40 °C to 85 °C with endurance of 2000 hours at 85 °C under rated voltage.
• Package & Mounting: Radial lead, can-style package in a φ5×11L size with 2 mm lead spacing for through‑hole assembly; supplied in bulk/bag packing.
• Compliance & Status: RoHS compliant. Lifecycle status: End of Life.

Typical Applications

• Entertainment Electronics: Compact smoothing and decoupling in consumer audio/video and entertainment devices where the UVR series is commonly specified.
• Power Supply Filtering: Local bulk decoupling and ripple suppression on mid-voltage rails using the specified ripple current ratings.
• Space‑Constrained Designs: Through‑hole applications requiring a small footprint and 2 mm lead spacing for dense PCB layouts.

Unique Advantages

• Miniature footprint: φ5×11L size and 2 mm lead spacing deliver capacitive functionality in tight board areas.
• Measured low leakage: 4.95 µA leakage simplifies bias and retention considerations in standby and low-current circuits.
• Defined ripple performance: Separate ripple ratings at 120 Hz and 10 kHz allow designers to assess both low- and high-frequency ripple handling.
• Elevated-temperature endurance: 2000 hours at 85 °C under rated voltage provides a clear baseline for reliability planning.
• RoHS compliant: Meets RoHS requirements for lead‑free manufacturing environments.
