type; PRWC=PRWC type.
水泥型前4 位表示产品类型,如果产品只有3个字母,第4位为0,例:PRW0=PRW 型; PRWC=PRWC 型。
2. 5th~ 6th digits (第5位~第6位):
a) This is to indicate the wattage or power rating. To distinguish the sizes and the numbers, the following codes are ud, and plea refer to the following chart for details: W
= Normal Size; S = Small Size; U = Ultra Small Size; “1” ~ “G” to denotes “1” ~ “16” as Hexadecimal:
表示产品标识功率,为区别不同尺寸,同时使用以下字母,如:W =正常尺寸; S =小尺寸; U =超小尺寸; “1” ~ “G” 代表 “1” ~ “16”为16进制。
b) For power rating less than 1W, the 5th digit will be the letters W, S or U to reprent the size required & the 6th digit will be a number or a letter code. Example: WA
= 1/10W; U2 = 1/2W-SS (功率小于1瓦, 第5位用W, S 或 U 表示尺寸要求,第6位将是数字或字母,例: WA = 1/10W; U2 = 1/2W-SS.).
学习机品牌c) For power rating of 1W to 16W, the 5th digit will be a number or a letter code and the 6th digit will be the letters of W, S or U. Example: AW = 10W; 3S = 3W-S.
当功率为1到16瓦, 第5位将是数字或字母,第6位是W, S or U. 例: AW = 10W; 3S = 3W-S.
d) For power rating between 20W to 99W, the 5th & 6th digits will show the whole numbers of the power rating itlf. Example: 20 = 20W; 75 = 75W.

3. The 7th digit is to denote the Resistance Tolerance. The following letter code is to be ud for indicating the standard Resisance Tolerance. As for Metal Film Fixed Resistor
products, it is also to denote the standard PPM as follows (第7位表示阻值误差。下列数码用来表示标准误差,用于金属膜产品时,同时用来表示标准PPM,如下): B= ±0.1% (15PPM) G= ±2% (100PPM)
C = ±0.25% (25PPM) J= ±5% (200PPM)
D= ±0.5% (50PPM) K = ±10%
F = ±1% (50PPM)
Remark: i f it it not one of the above standard "tolerance-TCR", the requirement should be clearly stated when placing order.
Example: ±1% (25PPM), the 7th digit still shows “F” but parately note the requirement of “25PPM”
