Metal Film Capped Ceramic Rod - Data Sheet
1. Scope
1.1 This specification for approve relates to the Metal Film Capped Ceramic Rod manufactured by UNI-ROYAL.
1.2 Filming in PCD technology.
1.3 Excellent Temperature coefficient, very low current noise.
1.4 Wide IRV range, suitable to produce high precision product.
2. Explanation of Part No. System
The standard Part No. includes 14 digits with the following explanation:
2.1 The 1st to 2rd digits are to indicate the product type .
Example: MF= Metal Film
2.2 The 3th digit is the type.
Example: C= Capped Filming Rod ；D= Uncapped Filming Rod
2.3 The 4th digit is the Alumina Content.
Example: 1= Alumina 70% ；2= Alumina 80% ；3= Alumina 85%
2.4 The 8th to 11th digits is to denote the Size of Rod.
Example: 1327=1.3×2.7 ; 1752=1.7×5.2 ; 1755=1.7×5.5 ; 1760=1.7×6.0 ; 2075=2.0×7.5 ; 2080=2.0×8.0 ; 2580=2.5×8.0;
