PLF1C181MDO1

The PLF1C181MDO1 is a radial-lead, conductive-polymer aluminum electrolytic capacitor designed for applications that require low ESR and high ripple-current handling. It is a polarized, standard radial-can part with a rated capacitance of 180 µF and a rated voltage of 16 V.

This device targets automotive and other demanding electronics where long life and thermal stability matter: it offers a load life of 2000 hours at 105°C and is AEC-Q200 qualified. Note: this product is scheduled for discontinuation and is not recommended for new designs.

Key Features

• Electrical Performance — 180 µF nominal capacitance with ±20% tolerance and 16 V rated voltage for decoupling and bulk energy storage.
• Low ESR — 9 mΩ measured at 100 kHz, supporting low-loss filtering and fast transient response.
• High Ripple-Current Capability — Rated ripple handling of 2.5 A at 120 Hz and 5 A at 100 kHz for continuous and high-frequency applications.
• Thermal Range and Endurance — Operating temperature range −55°C to +105°C with a load life of 2000 hours at 105°C; endurance specifications include capacitance and ESR limits after life test.
• Reliability and Qualification — AEC-Q200 qualified and compliant to RoHS (2011/65/EU, (EU)2015/863) for regulated applications.
• Package & Mounting — Radial lead, can-type package with 3.5 mm lead spacing and compact footprint (approx. 1.2 × 0.8 cm).
• Soldering Compatibility — Designed for lead-free flow soldering conditions; specified performance after resistance-to-soldering-heat testing is provided in the datasheet.
• Temperature Stability — Impedance stability across temperature: Z(+105°C)/Z(+20°C) ≤ 1.25 and Z(−55°C)/Z(+20°C) ≤ 1.25 at 100 kHz.

Typical Applications

• Automotive Power Electronics — Bulk decoupling and smoothing on DC–DC converter outputs and power rails where AEC-Q200 qualification and high ripple capability are required.
• ECU and Control Modules — Local energy storage and transient suppression for electronic control units operating across −55°C to +105°C.
• High-Frequency Power Filtering — Applications that benefit from low ESR at 100 kHz, such as switching regulator output filters and high-frequency power stages.

Unique Advantages

• Low measured ESR: 9 mΩ at 100 kHz reduces losses and improves regulator stability and thermal performance.
• High ripple-current handling: 5 A at 100 kHz (and 2.5 A at 120 Hz) enables reliable operation under high AC stress.
• Automotive-grade qualification: AEC-Q200 qualification supports use in automotive systems requiring component-level reliability documentation.
• Wide temperature and long-life rating: −55°C to +105°C range with 2000 hours at 105°C load life for sustained performance in harsh environments.
• Compact radial package: Small can footprint with 3.5 mm lead spacing for through-hole mounting and serviceability in space-constrained boards.
• RoHS and lead-free solder support: Compliant to RoHS and rated for lead-free flow soldering conditions to meet modern assembly requirements.
