PLG0G182MDO1

The PLG0G182MDO1 is a radial-lead conductive polymer aluminum solid electrolytic capacitor from Nichicon's PLG series. It provides higher capacitance in a compact through-hole can with low equivalent series resistance (ESR) and elevated ripple-current capability for general-purpose electronic designs.

Key attributes include a rated capacitance of 1.8 mF at 4 V, an operating temperature range of -55 °C to +105 °C, and a specified load life of 2000 hours at 105 °C. The part is RoHS compliant and supports lead-free flow soldering conditions. Note: this product is scheduled for discontinuation and is not recommended for new designs.

Key Features

• Capacitance & Voltage — Rated at 1.8 mF with a nominal voltage of 4 V and capacitance tolerance of ±20% (at 120 Hz, 20 °C).
• Low ESR — ESR specified at 9 mΩ measured at 100 kHz, enabling lower loss and improved high-frequency performance.
• High Ripple Current — Ripple current capability of 3.25 A at 120 Hz and 6.5 A at 100 kHz supports demanding AC current conditions.
• Thermal Endurance — Rated operating range from -55 °C to +105 °C with a load-life rating of 2000 hours at 105 °C; endurance criteria specify capacitance change within ±20% and tan δ/ESR ≤150% after endurance testing.
• Radial Lead Can — Through-hole radial lead mounting, polarized device in a can package with 3.5 mm lead spacing and compact dimensions (L: 1.2 × D: 0.8 cm).
• Soldering & Compliance — Compatible with lead-free flow soldering conditions and compliant with RoHS (2011/65/EU, (EU)2015/863).

Typical Applications

• Power supply filtering and smoothing — Low ESR and high ripple-current ratings make this capacitor suitable for bulk decoupling and smoothing in general-purpose power supplies and regulator circuits.
• High-frequency decoupling — ESR specified at 100 kHz supports decoupling tasks where reduced impedance at high frequencies is required.
• Energy hold-up and bulk storage — 1.8 mF capacitance provides bulk energy storage for short-term hold-up in consumer and industrial electronics.
• Through-hole assemblies and repairs — Radial-lead can package with standard lead spacing simplifies replacement and maintenance in existing through-hole board designs.

Unique Advantages

• High ripple tolerance: Dual-frequency ripple ratings (3.25 A at 120 Hz, 6.5 A at 100 kHz) enable reliable operation under significant AC load conditions.
• Low-loss performance: 9 mΩ ESR at 100 kHz reduces I²R losses and heat generation in high-current circuits.
• Long thermal endurance: 2000 hours at 105 °C load life with defined endurance limits for capacitance, tan δ, ESR, and leakage current supports stable performance in elevated temperatures.
• Through-hole form factor: Radial-lead can and 3.5 mm lead spacing provide mechanical robustness and straightforward assembly for legacy and repair applications.
• Regulatory compliance: Lead-free flow soldering condition correspondence and RoHS compliance support environmental and manufacturing requirements.

Why Choose PLG0G182MDO1?

PLG0G182MDO1 combines high capacitance, low ESR, and robust ripple-current capability in a compact radial-lead can, making it a practical choice for general-purpose power conditioning, decoupling, and energy-hold applications where through-hole mounting is preferred. Its specified 2000-hour load-life at 105 °C and defined endurance limits provide engineers with measurable reliability parameters for thermal-stress environments.

This part is suitable for designers and maintenance engineers updating or repairing existing through-hole boards that require a high-capacitance, low-ESR solution. As the product is scheduled for discontinuation and not recommended for new designs, it is particularly applicable for legacy-support, spares, and replacement scenarios.
