The **TDC10-1-R** is a high-performance, time-delay cartridge fuse manufactured by **Eaton (Bussmann Series)**. It is specifically designed for primary circuit protection in electronic equipment where high surge currents are common. --- ### ## Technical Specifications The following table summarizes the key electrical characteristics of the TDC10-1-R: | Parameter | Value | | :--- | :--- | | **Rated Current** | 1 Ampere | | **Voltage Rating (AC)** | 250 Volts | | **Characteristic** | Time-Delay (Slow-Blow) | | **Body Material** | Ceramic | | **Mounting Style** | Holder / Clip (Cartridge) | | **Dimensions** | 6.3mm x 32mm (1/4" x 1-1/4") | | **Interrupt Rating** | 35A @ 250Vac | | **RoHS Compliant** | Yes | --- ### ## Key Electronic Features #### 1. Time-Delay Mechanism The "Time-Delay" (also known as "Slow-Blow") characteristic means the fuse can withstand brief, high-current surges (inrush currents) without blowing. This is essential for circuits containing **transformers or motors** that draw significant power only at startup. #### 2. Ceramic Construction Unlike glass fuses, the TDC10 series uses a **ceramic tube**. Ceramic provides: * **High Breaking Capacity:** It can handle higher fault currents without shattering. * **Arc Suppression:** The internal filler (often silica sand) helps extinguish the electrical arc during a short circuit. #### 3. Termination and Form Factor The fuse features nickel-plated brass end caps for high conductivity and corrosion resistance. Its 6.3 x 32mm dimensions are a global standard, making it compatible with a wide variety of panel-mount and PCB-mount fuse holders. --- ### ## Typical Applications * **Power Supplies:** Protecting the AC input side of switch-mode power supplies. * **Industrial Controls:** Protecting small motors and solenoids. * **Consumer Electronics:** Used in high-end audio equipment and appliances where surge protection is required. --- ### ## Part Number Breakdown * **TDC10:** Series Identifier (6.3 x 32mm Ceramic Time-Delay). * **1:** Amperage Rating (1A). * **-R:** RoHS Compliant version.
