KC73133C 1/3 INCH CCD IMAGE SENSOR FOR VGA COMPATIBILITY INTRODUCTION 16Pin Cer DIP The KC73133C is an interline transfer progressive scan type square pixel CCD area image sensor of 1/3 inch optical format developed for VGA. The electron accumulation time can be changed by the electronic shutter function and it is possible to obtain a frame still image without a mechanical shutter. High resolution and good color reproduction are accomplished by using mosaic R, G, B primary color filters. It is suitable for still cameras and PC input cameras.

Package Dimensions 18 KC73133C 1/3 INCH CCD IMAGE SENSOR FOR VGA COMPATIBILITY HANDLING INSTRUCTIONS • Static Charge Prevention CCD image sensors can be easily damaged by static discharge. Before handling, be sure to take the following protective measures. — Use non chargeable gloves, clothes or material. Also use conductive shoes. — When handling directly, use an earth band. — Install a conductive mat on the floor or working table to prevent generation of static electricity. — Ionized air is recommended for discharging when handling CCD image sensor. — For the shipment of mounted substrates, use boxes treated for the prevention of static charges. • Soldering — Make sure the package temperature does not exceed 80 °C. — Solder dipping in a mounting furnace causes damage to the glass and other defects. Use a grounded 30W soldering iron and solder each pin in less than 2 seconds. For repairs and and remount, cool sufficiently. — To dismount an imaging device, do not use a solder suction equipment. When using an electronic disoldering tool, use a thermal controller of the zero cross on/off type and connect to ground. • Dust and Dirt Protection — Operate in the clean environments (around class 1000 will be appropriate). — Do not either touch glass plates by hand or have object come in contact with glass surface. Should dirt stick to a glass surface blow it off with an air blow (for dirt stuck through static electricity ionized air is recommended). — Clean with a cotton bud and ethyl alcohol if the glass surface is grease stained. Be caerful not to scratch the glass. — Keep in case to protect from dust and dirt. To prevent dew condensation, preheat or precool when moving to a room with great temperature differences. — When a protective tape is applied before shipping, just before use remove the tape applied electrostatic protection. Do not reuse the tape. • Do not expose to strong light (sun rays) for long period, color filter are discolored. • Exposure to high temperature or humidity will affect the characteristics. accordingly avoid storage or usage in such conditions. • CCD image sensors are precise optical equipment that should not be subject to mechanical shocks. 19
