The **ME64ZAG-R** is an electronic component primarily classified as a **Precision Thin Film Chip Resistor Network** (or array), typically manufactured by **Susumu**. These components are designed for high-precision circuits where stability and tight tolerances are critical. --- ## 1. Technical Specifications The following table outlines the general electronic characteristics of the ME64ZAG-R series: | Parameter | Typical Value / Specification | | :--- | :--- | | **Component Type** | Thin Film Chip Resistor Network | | **Configuration** | 4-Resistor Array (typically) | | **Resistance Tolerance** | ±0.1% (High Precision) | | **TCR (Temperature Coefficient)** | ±25 ppm/°C (Highly Stable) | | **Operating Temperature** | -55°C to +125°C | | **Mounting Type** | Surface Mount (SMD/SMT) | | **Substrate Material** | Alumina Ceramic | --- ## 2. Key Electronic Features * **Thin Film Technology:** Unlike standard thick film resistors, thin film provides significantly lower noise and better long-term stability. * **Matching Accuracy:** Because the resistors are integrated onto a single substrate, they track each other’s temperature changes almost perfectly. This makes them ideal for voltage dividers. * **Sulfur Resistance:** The "ZAG" designation often implies high reliability and resistance to environmental pollutants like sulfur, which can cause corrosion in standard resistors. * **Compact Integration:** By combining multiple resistors into one package, it saves PCB real estate and reduces the component count for pick-and-place machines. --- ## 3. Common Applications Due to its high precision, the ME64ZAG-R is found in: 1. **Instrumentation:** Signal conditioning and measurement tools. 2. **Medical Equipment:** Devices requiring stable voltage references. 3. **Automotive Electronics:** Sensors and control units that operate in harsh environments. 4. **Communication Base Stations:** High-frequency signal processing circuits. --- ## 4. Part Number Breakdown (Typical) While internal codes vary by manufacturer, the prefix generally indicates: * **ME:** Series name (Susumu Precision Array). * **64:** Physical dimensions/case size. * **ZAG:** Material composition and tolerance grade (High stability). * **R:** Packaging code (usually Tape and Reel). ---
