MF-R010

The MF-R010 is part of Bourns' Multifuse® family of Polymer Positive Temperature Coefficient (PPTC) resettable fuses. These components are designed to protect electronic circuits from overcurrent conditions. When exposed to a fault condition, the fuse transitions from a low-resistance state to a high-resistance state, thereby limiting the current flow. Once the fault condition is removed, the fuse resets itself to the low-resistance state.

Key Features

• Current Rating:
  • Hold Current (Ihold): 0.10 A - The maximum current the fuse can carry indefinitely without tripping.
  • Trip Current (Itrip): 0.20 A - The minimum current that will cause the fuse to trip and transition to a high-resistance state.
• Maximum Voltage: 60V - The maximum voltage that can be applied across the fuse without causing damage.
• Resistance:
  • Initial Resistance (Rmin): 1.5Ω
  • Maximum Resistance (Rmax): 6.5Ω
  • Post-Trip Resistance (R1max): 15Ω - The resistance after the fuse has tripped and reset.
• Time to Trip: Varies depending on the current applied but generally within seconds for overcurrent conditions.
• Operating Temperature: -40°C to +85°C - Suitable for a wide range of environmental conditions.
• Physical Size: Radial leaded package, compact for easy PCB integration.

Applications

• Consumer Electronics: Protects circuits in devices such as smartphones, tablets, and wearable technology.
• Industrial Equipment: Ensures safe operation of machinery and control systems.
• Automotive Electronics: Provides overcurrent protection in automotive control units and sensor systems.
• Telecommunications: Protects networking equipment, modems, and other communication devices.
• Power Supplies: Integral in preventing overcurrent conditions in power management circuits.
