UPM1H6R8MDD

The UPM1H6R8MDD is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon's UPM series designed for low-impedance power decoupling and filtering. It is a radial-lead, polarized capacitor specified at 6.8 µF and 50 V with compact dimensions for space-constrained designs.

Targeted at applications that require stable performance across a wide temperature range, the part combines defined loss characteristics, controlled leakage and rated ripple current to support demanding embedded and automotive-related systems.

Key Features

• Capacitance & Voltage: 6.8 µF nominal capacitance at a rated voltage of 50 V with capacitance tolerance of -20% to +20%.
• Low-impedance design: UPM series low-impedance construction with specified tangent of loss angle (tanδ) of 0.10 measured at 20°C, 120 Hz for consistent AC performance.
• Ripple current ratings: Low-frequency ripple current 22.5 mA at 120 Hz and high-frequency ripple current 45 mA at 200 kHz, supporting bulk decoupling and suppression of supply noise.
• Leakage current: Specified leakage current of 10.2 µA for predictable bias behavior in DC applications.
• Mechanical & mounting: Radial lead package, size φ5 × 11 mm (D: 0.5 cm × L: 1.1 cm) with 2.0 mm lead spacing (±0.5 mm), supplied in bulk or bag packing.
• Temperature & endurance: Operating range from -55°C to +105°C and rated life of 2000 hours at 105°C, enabling use in elevated-temperature environments.
• Qualification & compliance: AEC-Q200 rating and RoHS compliance as listed in the product specifications.

Typical Applications

• Automotive electronic modules: AEC-Q200 qualification and wide temperature range make this capacitor suitable for decoupling and filtering in automotive control and sensing modules.
• Embedded power rails: Compact radial-lead form factor provides local bulk decoupling and ripple attenuation on PCB power rails in compact embedded systems.
• Industrial control electronics: Stable leakage and defined ripple current support smoothing and transient suppression in industrial power supplies and control boards.

Unique Advantages

• Small footprint for high-voltage applications: 6.8 µF at 50 V in a φ5 × 11 mm package helps reduce board area compared with larger through-hole capacitors.
• Predictable AC performance: Specified tanδ at 20°C/120 Hz supports predictable loss characteristics for filter and timing circuits.
• Defined ripple handling: Separate low- and high-frequency ripple current specs enable designers to evaluate performance across the noise spectrum.
• Wide operating temperature: -55°C to +105°C rating supports deployment in harsh and variable-temperature environments.
• Automotive-capable qualification: AEC-Q200 listing simplifies selection for designs targeting automotive or similarly demanding applications.
• Regulatory compliance: RoHS compliance supports use in environmentally regulated designs.
