Overview
The B57136S0309M100 is an NTC thermistor from the S36 series designed for inrush current limiting. It features a nominal resistance of 3 ohms at 25°C and supports a maximum steady-state current of 30A. The component has a disc diameter of 39mm (1.535 inches) and can absorb up to 750J of energy. It is UL recognized.
Feature Summary
- Negative Temperature Coefficient (NTC) design for effective inrush current suppression
- High energy absorption capability suitable for demanding power applications
- Robust construction with a 39mm disc form factor
Applications
- Power supply input stages
- Industrial equipment protection
- Consumer electronics power management
Procurement Notes
Verify the specific manufacturer designation, as TDK Electronics has discontinued the EPCOS brand for passive components. Ensure the ordering suffix matches the required tolerance and packaging configuration. Confirm that the 3-ohm resistance and 30A current ratings align with the target circuit requirements before finalizing procurement.
Selection Notes
Select this component when a 3-ohm cold resistance is required to limit initial charging currents. The 30A steady-state rating and 750J energy absorption capacity define its suitability for medium-power applications. Consider the 39mm physical size for board space constraints and thermal management needs during operation.
Part Context
This part belongs to the S36 series of inrush current limiters manufactured by TDK Electronics. Historically associated with the EPCOS brand, these components are widely used for protecting electronic circuits against high startup currents. The series offers standardized dimensions and electrical characteristics for reliable integration into various power systems.
Replacement Considerations
Check for direct substitutes within the S36 series or equivalent NTC thermistors with matching 3-ohm resistance and 30A current ratings. Verify compatibility regarding energy absorption capabilities and physical footprint to ensure seamless replacement without redesigning the host circuit.
