Overview
The TOKO 187LY-273J is a fixed inductor designed for applications demanding precise energy storage and filtering characteristics. Its primary function is to impede AC current while allowing DC current to pass, critical for smoothing power supply ripple and shaping signal responses. A key design consideration for inductors of this type is the trade-off between inductance value and DC resistance (DCR); achieving a high inductance of 27mH, as seen in the 187LY-273J, often necessitates a higher DCR (80 Ohms Max), which can impact power efficiency in high-current circuits. This unshielded, radial-mount component is engineered for robust performance within its specified operating parameters.
Key Features
- Inductance: 27mH
- Tolerance: ±5%
- Current Rating: 30mA
- DC Resistance (DCR): 80 Ohm Max
- Q Factor: 100 @ 79.6kHz
- Dimensions: 0.315″ Dia x 0.441″ H (8.00mm x 11.20mm)
Applications
The component is engineered for deployment in systems requiring high reliability and performance under specific operating conditions. It provides functional stability across the stated design envelope.
- Low-frequency signal filtering in audio preamplifiers
- Energy storage elements in switch-mode power supply (SMPS) output stages
- Choke coils for RF impedance matching networks
- Noise suppression in control circuitry for sensitive instrumentation
