The **PTPH-1GG-R/CE** is a specialized electronic component, specifically a **high-precision, high-voltage film resistor** often used in automotive, industrial, and high-frequency applications. ### 1. General Specifications This component belongs to a class of passive resistors designed to handle significant electrical stress while maintaining tight tolerances. | Parameter | Specification (Typical) | | :--- | :--- | | **Component Type** | Precision Thick Film Resistor | | **Resistance Value** | 1 Gigaohm (1GΩ) | | **Tolerance** | ±1% to ±5% (depending on specific batch code) | | **Package/Case** | Radial Leaded / Through-hole | | **Operating Temp** | -55°C to +155°C | | **Voltage Rating** | High Voltage (up to several kV) | --- ### 2. Key Electronic Features * **High Resistance Stability:** The "PTPH" series is known for low Temperature Coefficient of Resistance (TCR), meaning the resistance value does not drift significantly as the part heats up. * **Voltage Coefficient:** These parts are engineered to minimize the "Voltage Coefficient of Resistance" (VCR), ensuring the resistance remains linear even at high potential differences. * **Environmental Protection:** The "CE" suffix typically indicates a conformal coating or specific encapsulation that protects the ceramic core and resistive film from moisture, dust, and electrical arcing. * **RoHS Compliance:** The "-R" designation usually confirms that the part is Lead-Free and RoHS compliant. --- ### 3. Common Applications Due to its high resistance (1GΩ) and high voltage rating, this part is used in: 1. **Mass Spectrometry:** Providing stable reference voltages. 2. **X-Ray Power Supplies:** Used in voltage divider networks for monitoring high-output voltages. 3. **High-Impedance Buffers:** In sensitive measuring equipment where leakage current must be minimized. 4. **Automotive Ignition Systems:** Used for EMI/RFI suppression. --- ### 4. Part Number Breakdown (Generic) While manufacturers have unique codes, the string generally follows this logic: | Segment | Meaning | | :--- | :--- | | **PTPH** | Product Series (Precision Thick Film High Voltage) | | **1GG** | 1 Gigaohm (Giga-Ohm) | | **-R** | RoHS Compliant / Lead-Free | | **CE** | Conformal Encapsulation / Epoxy Coating |
