The term **136-R** in the electronics industry typically refers to specific passive components, most commonly **thick film chip resistors** or **high-frequency capacitors**, depending on the manufacturer’s prefix. Below is a detailed breakdown of the most common electronic parts associated with the "136-R" designation. --- ## 1. Thick Film Chip Resistors (Typical Identification) In resistor manufacturing (like those from **Yageo** or **Vishay**), "136-R" is often part of a series or a specific value code. ### Specifications Table | Feature | Standard Specifications | | :--- | :--- | | **Component Type** | Surface Mount Device (SMD) Resistor | | **Resistance Value** | Usually denotes 136 Ohms (if used as a value code) | | **Tolerance** | $\pm 1\%$ or $\pm 5\%$ | | **Power Rating** | 1/10W (0603) to 1/4W (1206) | | **Material** | Ruthenium oxide (Thick Film) | --- ## 2. Panasonic ECQ-V Series (Capacitors) Historically, the "136" code appears in Japanese capacitor series, specifically the **ECQ-V Stacked Metallized Film Capacitors**. ### Technical Characteristics * **Dielectric:** Polyester film. * **Capacitance Value:** 0.13 $\mu$F (indicated by the 136 code where 13 followed by 6 zeros in pF). * **Application:** General-purpose coupling, decoupling, and noise suppression in consumer electronics. --- ## 3. Connector and Hardware Variants In the realm of electromechanical parts, **136-R** is frequently associated with specialized connectors: ### D-Sub or Circular Connector Backshells * **Manufacturer:** Common in military-grade parts (like Glenair or Amphenol). * **Function:** Provides strain relief and EMI/RFI shielding for cable assemblies. * **Finish:** The "R" often signifies **Electroless Nickel** or a specific RoHS-compliant plating. --- ## Summary of Usage Cases Depending on your specific board, here is how to identify the part: 1. **If it’s a small black rectangle:** It is an SMD Resistor (136 Ohms). 2. **If it’s a small reddish/brown box:** It is a 0.13 $\mu$F Film Capacitor. 3. **If it’s a metal housing on a cable:** It is a Connector Backshell. ---
