Overview

Murata Manufacturing Co., Ltd. has started mass production of 0805-size (2.0 x 1.25mm) monolithic ceramic capacitors packaged in narrow-pitch (2mm) embossed tape.

Features

The conventional 0805-size monolithic ceramic capacitors are packaged in a 4mm-pitch embossed tape that holds 10,000 pieces per reel with a diameter (mm) of Φ 330. These new products are packaged in a narrow-pitch (2mm) embossed tape that holds double the quantity per reel (20,000 pieces per reel) of the same Φ 330-mm diameter. Therefore, this packaging is more eco-friendly and also saves space. This packaging can also reduce the frequency of changing the reel by the customer. Also note that the same embossed tape can be used for 0805-size 22µF capacitors.

1. Eco-friendly

• Reduces packaging material usage (resource saving)
  
• Reduces packaging waste
  
• Reduces the energy required for transportation (global warming countermeasures)
  

2. Space-saving

• Reduces storage/stock space
  
• Conventional-pitch (4mm) taping product → Narrow-pitch (2mm) taping product
  

Background

Murata has been endeavoring to adopt narrow-pitch taping for the packaging of all sizes of products starting with the packaging of the 01005-size (0.4 x 0.2mm) products in 4mm-width, 1mm-pitch embossed tape. While we were making these efforts, we received a request from a customer who uses narrow-pitch taping (8mm-width, 1mm-pitch paper tape) for 0201-size (0.6 x 0.3mm) and 0402-size (1.0 x 0.5mm) products. This customer told us about wanting to adopt narrow-pitch taping also for 0805-size products - which are large capacitance products with a lot of demand from customers - in order to reduce the frequency of changing the reels. To respond to this customer's request, we decided to develop 2mm-pitch embossed tape for packaging 0805-size products together with our tape manufacturer.

During this endeavor, we were faced with the following issues. The development of 2mm-pitch embossed tape for packaging 0805-size products is considered to be extremely difficult. We did, however, successfully develop the 2mm-pitch embossed tape after much trial and error in the joint effort with the tape manufacturer and optimizing the die shape and molding conditions.
Dies used for molding embossed tape get damaged easily.
Tape get torn easily because part of the tape is thin.
Cannot provide sufficient height of the rib (wall) between the pockets used for inserting a chip.
Applications

0805-size monolithic ceramic capacitors are used for many products such as small mobile devices that require large capacitance as well as personal computers, digital cameras, TVs, and automobiles.

Production

Mass production started at Fukui Murata Manufacturing Co., Ltd. from July 2013.

Terminology

*Embossed tape: This tape uses resins such as polystyrene and polycarbonate and the chips are stored in a tape that has been molded into a pocket shape.
