1. Product Overview:

️· The document is a product guide for SAHA Mica Capacitors, detailing their specifications, performance characteristics, and testing procedures.
️· SAHA capacitors aim to meet commercial specifications and, in some cases, military specifications (MIL-C-5).

2. Key Performance Characteristics & Measurement:

️· Capacitance: Measured at 1 MHz ±10% for values up to 1000 pF, and 1 kHz ±10% for values above 1000 pF.
️· Dissipation Factor: Measured at 1 MHz (≤1000 pF) and 1 kHz (>1000 pF).
️· Insulation Resistance: Measured at 50-100V DC. Significant testing is done to assess its variation under different conditions (temperature, after tests).
️· Withstanding Voltage: Designed to handle 200% of rated voltage for a short duration (1-5 seconds)

3. Rigorous Testing Procedures:

The document details a comprehensive set of tests designed to ensure the reliability and performance of the capacitors. These tests include:

️· Vibration Test: Assessing durability under harmonic motion.
️· Soldering Heat Resistance Test: Checking performance after exposure to high temperatures.
️· Moisture Resistance Tests: (various types, including with and without applied voltage) Evaluating performance under high humidity.
️· Life Test: Long-duration testing at elevated temperature and voltage.

4. Performance Expectations after testing:

️· Insulation Resistance: Needs to stay above 30000 M Ohms (for capacitances up to 10000pF) after vibration testing.
️· Dissipation Factor: Remains within specified limits after testing.
️· Capacitance Change: Allowed tolerances vary depending on the test and capacitor characteristics (typically ±1% or ±1 pF, but can be higher).

5. Visuals/Graphs:

The document heavily references a series of figures/graphs (Figures 1-14) that show the variations in performance characteristics (capacitance, dissipation factor, insulation resistance) under different conditions and throughout the testing process. These figures illustrate expected performance patterns.

6. Marking Types:

️· Type 1: Capacitance in pF, tolerance, and voltage are marked.
️· Type 2: (Discontinued) Previously for military capacitors.
️· Type 3: Capacitance code and tolerance code are marked.

In essence, this document serves as a technical reference for engineers and purchasers who need detailed information about the quality control and performance characteristics of SAHA Mica Capacitors.
