The part number **4601-059** typically refers to a specific series of **EMI/RFI Feedthrough Filters** manufactured by companies like **Tusonix (a subsidiary of CTS Electronic Components)**. These components are critical in electronic circuits for suppressing high-frequency noise while allowing DC or low-frequency signals to pass through a chassis or bulkhead. --- ### 1. Component Overview Feedthrough filters are essentially specialized capacitors designed to provide a low-impedance path to ground for high-frequency interference. | Feature | Specification Details | | :--- | :--- | | **Component Type** | Feedthrough Capacitor / EMI Filter | | **Configuration** | C-Type (Single Element) | | **Mounting Style** | Solder Mount (Bushless) | | **Common Application** | Telecommunications, Medical Equipment, Aerospace | ### 2. Technical Characteristics While specific values can vary slightly based on the manufacturer's exact revision, the 4601 series generally follows these parameters: * **Capacitance:** Usually ranges from 10pF to 10,000pF depending on the specific sub-suffix, though the -059 variation often sits in the mid-range for broad-spectrum filtering. * **Voltage Rating:** Typically rated for **100V to 500V DC** (Working Voltage). * **Temperature Range:** Operates effectively between **-55°C and +125°C**. * **Physical Housing:** Features a silver-plated or gold-plated brass body for high conductivity and ease of soldering. ### 3. Visual and Mechanical Design The "4601" series is known for its miniature profile, making it ideal for high-density electronic assemblies. 1. **Inner Lead:** A central conductor that carries the signal. 2. **Ceramic Dielectric:** Surrounds the conductor to provide the capacitance. 3. **Outer Body:** A metal sleeve that is soldered directly into a hole in a metal shield or partition. --- ### 4. Why Use the 4601-059? In complex electronic systems, cables act like antennas, picking up electromagnetic interference (EMI). The 4601-059 is used to: * **Shield Integrity:** Maintain the shielding effectiveness of an enclosure. * **Signal Purity:** Prevent high-frequency digital noise from escaping a device. * **Regulatory Compliance:** Help devices meet FCC or CE requirements regarding electromagnetic radiation.
