UPM1H3R3MDD

The UPM1H3R3MDD is a radial‑lead aluminum electrolytic capacitor from Nichicon’s UPM series. As part of the UPM family it carries the series characterization of low impedance and high reliability, and is supplied in a compact φ5 × 11 mm can with 2.0 mm lead spacing.

Designed for electrically demanding environments, this polarized capacitor is rated 3.3 µF at 50 V, specified for operation from −55 °C to 105 °C, and is AEC‑Q200 qualified with RoHS compliance. Note: this part is listed as End Of Life.

Key Features

• Capacitance & Voltage: 3.3 µF nominal capacitance with a 50 V rated voltage and ±20% tolerance at 20 °C, 120 Hz.
• UPM Series Characteristics: Series designation indicates low impedance and high reliability consistent with UPM family performance statements.
• High temperature range and endurance: Operating temperature −55 °C to 105 °C with a rated life/endurance of 2000 hours at 105 °C for this part.
• Loss and leakage: Tangent of loss angle (tan δ) specified at 0.10 (measured at 20 °C, 120 Hz) and leakage current specified as 4.95 µA.
• Ripple handling: Ripple current ratings of 16.5 mA at 120 Hz (low frequency) and 33 mA at 1 kHz (high frequency).
• Form factor & mounting: Radial lead mounting in a φ5 × 11 mm can, lead spacing 2.0 mm (±0.5 mm), supplied as Bulk (No Terminal Forming) or Bag Packing.
• Compliance and qualification: AEC‑Q200 rated and RoHS compliant.
• Polarized device: Intended for polarized circuit applications; observe polarity during assembly.
• Lifecycle status: Product is End Of Life—suitable for legacy support and limited‑availability requirements.

Typical Applications

• Automotive electronics: Specified for automotive applications and AEC‑Q200 qualified for designs that reference automotive component requirements.
• Power supply smoothing: Compact capacitance and rated voltage suitable where decoupling or smoothing is required in constrained assemblies.
• Embedded and industrial electronics: Radial lead form factor and wide operating temperature range support use in embedded modules and industrial control units.

Unique Advantages

• Compact radial package: φ5 × 11 mm can and 2.0 mm lead spacing provide a small footprint for space‑constrained PCBs and through‑hole prototypes.
• Temperature and endurance specification: Rated to −55 °C to 105 °C with a 2000‑hour endurance at 105 °C, enabling use in elevated‑temperature environments within the stated life limit.
• Measured loss and leakage: Low tan δ (0.10 at 20 °C, 120 Hz) and a low leakage current (4.95 µA) support stable electrical performance in bias applications.
• Ripple capability across frequencies: Defined ripple current values at both 120 Hz and 1 kHz help match the device to expected AC stress in power circuits.
• Automotive‑grade qualification: AEC‑Q200 rating provides a recognized qualification level for designs that require that standard.
• RoHS compliant: Meets RoHS requirements for regulated substance control in modern assemblies.

Why Choose UPM1H3R3MDD?

UPM1H3R3MDD brings the UPM series’ low‑impedance, high‑reliability characteristics into a compact radial can, delivering 3.3 µF at 50 V with controlled loss and leakage parameters. Its AEC‑Q200 rating and −55 °C to 105 °C operating range make it appropriate for applications that require automotive‑level qualification and elevated temperature operation within the specified lifetime.

This part is well suited to engineers supporting legacy designs or limited‑availability replacements who require clear electrical specifications (tan δ, leakage, ripple currents) and a small through‑hole footprint. Because the part is End Of Life, consider availability and lifecycle planning when specifying it into new designs.
