Re: Request for discontinuance of Precious metal electrode type MLCC(medium volt)

(Medium voltage Monolithic Ceramic Capacitor) Dear Sir and/or Madam, Thank you for your usual patronage on our ceramic capacitor. We would like to notify you of the discontinuance of Murata MLCC / Precious metal electrode type as shown below. Please kindly review this document for the details of the request. 1. Object items : Medium Voltage MLCC(Chip Monolithic Ceramic Capacitor (Precious metal electrode type)

DC200V & DC500V of High Dielectric type and Low loss type Object series : GRM/GRG series Rated voltage : DC200V, DC500V Temp. Characteristic and Cap. : X7R/X7F/W5R/W5F-char. 、△C-char. (C0G) 10pF and over Murata part number : GR* *** ** 2D *** * Y***, GR* *** ** 2H *** * Y***

: GR* *** ** 2D *** * V***, GR* *** ** 2H *** * V***

2. Discontinue Schedule

Dead line of one shot last order : Sep. 30 2013 Date of last shipment : Mar. 31 2014 Please return this form with your signature by Mar. 31 2013 *Please feel free to contact us, if you have any question, or request on our proposal.

3. Reason To improve the productivity for stable supply and to avoid the risk from the influence of precious

metal market on supply and cost. Murata has been expanding the products that are used base metal for Inner electrode material BME

product as standard products. We would like to unify PME(precious metal) product and BME product to improve the productivity for stable supply.

4. Proposal of Substitute product We would like to propose the substitute products. Please find attached list.

Please confirm the deviation point described in the list. As for structure and material, please refer to the following table.
