615
The Littelfuse 0603L035YR is a PTC (Positive Temperature Coefficient) resettable fuse designed to provide reliable overcurrent protection in a compact form factor. This surface-mount device (SMD) is ideal for applications where space is limited but robust protection is essential. Here are its key advantages, product highlights, and application scope:

**Advantages:**
1. **Resettable Functionality:** Unlike traditional fuses, the 0603L035YR automatically resets after the fault condition is removed, reducing maintenance and replacement costs.
2. **Compact Size:** With a 0603 package size (1.6mm x 0.8mm), it is perfect for modern, miniaturized electronics.
3. **Fast Response Time:** It quickly responds to overcurrent conditions, minimizing potential damage to sensitive components.
4. **Low Resistance:** Its low initial resistance ensures minimal power loss during normal operation.
5. **Wide Operating Temperature Range:** It performs reliably in temperatures ranging from -40°C to +85°C, making it suitable for diverse environments.

**Product Highlights:**
- **Hold Current (IH):** 350mA, ensuring protection for low-current circuits.
- **Trip Current (IT):** 700mA, providing a safety margin for transient surges.
- **Voltage Rating:** 6V, suitable for low-voltage applications.
- **RoHS Compliance:** Environmentally friendly and meets global regulatory standards.

**Application Scope:**
The 0603L035YR is widely used in consumer electronics, telecommunications, and industrial equipment. It is particularly effective in protecting USB ports, battery packs, and power management circuits. Its small size and resettable nature make it a preferred choice for portable devices like smartphones, tablets, and wearables. Additionally, it is used in automotive electronics, IoT devices, and LED lighting systems, where reliable overcurrent protection is critical.

In summary, the Littelfuse 0603L035YR PTC resettable fuse combines compact design, resettable functionality, and robust performance, making it an essential component for modern electronic systems.
