LKG1E103MESCBK

The LKG1E103MESCBK is an aluminum electrolytic, snap‑in terminal capacitor from Nichicon’s LKG series, specified at 10,000 µF and 25 V with ±20% tolerance. It is designed specifically for high‑grade audio equipment and HD Audio applications where audible performance and reliable bulk capacitance are priorities.

This part is the LKG series TYPE‑II (BK) center grade, engineered to deliver the series’ balanced audio characteristics while providing robust electrical and environmental performance: rated for operation from -40 °C to +85 °C, RoHS compliant, and with a 1,000‑hour endurance at 85 °C.

Key Features

• Core Type 
  Aluminum electrolytic, snap‑in (radial can) construction for PCB mounting and mechanical stability.
• Audio‑Focused Grade (TYPE‑II – BK) 
  Center grade of the LKG series (code BK), described by the series as providing the best sound via electrode foil construction for multiple use in audio applications.
• High Bulk Capacitance 
  10,000 µF capacitance at 25 V with ±20% tolerance to deliver significant energy storage in audio power stages and related circuits.
• Electrical Loss and Ripple 
  Specified tan δ = 0.3 (measurement at 120 Hz, 20 °C) and rated ripple current 3.3 A at 120 Hz, supporting sustained AC loading typical in audio supplies.
• Temperature & Endurance 
  Operating range -40 °C to +85 °C and endurance specified as 1,000 hours at 85 °C; post‑endurance limits: capacitance change within ±20%, tan δ ≤ 200% of initial, leakage current ≤ initial value.
• Leakage Current Specification 
  Leakage current after 5 minutes at rated voltage at 20 °C is specified as not more than 3√(C·V) µA (C: µF, V: V), per series datasheet.
• Size & Marking 
  Physical size φ35 × 30L mm (height seated max 1.181 inch); black sleeve with gold‑color printed marking for clear identification.
• Compliance 
  RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• High‑Grade Audio Equipment 
  Used where prioritized fidelity and audible performance are required in consumer and professional audio designs.
• HD Audio Systems 
  Suited to audio subsystems and components that specify LKG series tone quality and stability over typical audio operating conditions.
• Audio‑Focused Electronic Modules 
  Appropriate for modules and assemblies in which large bulk capacitance and the LKG series’ graded audio characteristics are desired.

Unique Advantages

• Audio‑grade tuning (TYPE‑II BK) 
  Delivered as the LKG series center grade (BK), providing the series’ intended balance of sound quality and versatility.
• Large energy storage in a compact can 
  10,000 µF at 25 V supplies substantial bulk capacitance within a φ35 mm package for designs that need reservoir capacity.
• Measured performance for audio environments 
  tan δ specified at 0.3 (120 Hz, 20 °C) and a 3.3 A ripple current rating at 120 Hz provide defined loss and AC handling characteristics.
• Thermal endurance and stability 
  Rated for -40 °C to +85 °C with a 1,000‑hour endurance at 85 °C and defined post‑endurance limits for capacitance, tan δ, and leakage.
• RoHS compliance 
  Meets RoHS requirements (2011/65/EU, (EU)2015/863) for hazardous substance control in electronics assemblies.
• Clear identification 
  Gold‑color printing on a black sleeve simplifies part recognition during assembly and maintenance.
